A nurse is preparing to administer amoxicillin 500 mg PO four times a day to a client. The amount available is amoxicillin suspension 250 mg/5 mL. How many mL should the nurse administer per dose?
Correct answer
10
Rationale
The correct answer is 10 mL. To calculate this, we first find the total daily dose of amoxicillin (500 mg x 4 doses = 2000 mg). Then, we convert this to mL using the concentration of the suspension (250 mg/5 mL). 2000 mg ├À 250 mg/mL = 8 mL per dose. Since the question asks for the total mL per dose, we multiply 8 mL by 1.25 (to account for 500 mg instead of 400 mg), giving us 10 mL. Other choices are incorrect because they do not follow the correct conversion process or do not consider the total daily dose of amoxicillin needed.
